- The terms antioxidants and free radicals are being used more and more by nutritionists and other health professionals. Antioxidants are compounds that are thought to be good for you and free radicals are harmful.n general, antioxidants neutralize free radicals that are generated in the body and prevent damage to cell proteins, lipids and carbohydrates. Antioxidants can be water-soluble or lipid-soluble, thus some exist within the lipid or within the water portion of cells.

- Antioxidants are chemicals that interact with and neutralize free radicals, thus preventing them from causing damage. Antioxidants are also known as “free radical scavengers.”. The body makes some of the antioxidants it uses to neutralize free radicals.These antioxidants are called endogenous antioxidants. However, the body relies on external (exogenous) sources, primarily the diet, to obtain the rest of the antioxidants it needs.he body makes some of the antioxidants it uses to neutralize free radicals.

Antioxidants: In Depth Antioxidants are man-made or natural substances that may prevent or delay some types of cell damage. Diets high in vegetables and fruits, which are good sources of antioxidants, have been found to be healthy; however, research has not shown antioxidant supplements to be beneficial in preventing diseases.

A Doctorâs Treasury of An antioxidant, like resveratrol, is any molecule that is stable with or without all its necessary electrons. A free radical, on the other hand, is a molecule that is unstable … when it loses an electron. The purpose of an antioxidant is to donate one of its electrons to the unstable free radicals.n its way round the body, the nutrients in the blood are absorbed into the places where they are needed. To sum this up, the body absorbs the nutrients into the blood through capillaries in the intestines.

Antioxidant Antioxidants that are reducing agents can also act as pro-oxidants. For example, vitamin C has antioxidant activity when it reduces oxidizing substances such as hydrogen peroxide, however, it will also reduce metal ions that generate free radicals through the Fenton reaction.

What Are Antioxidants? | Antioxidant benefits | Antioxidants Foods | Antioxidants In Tea. As free radicals (see below) have deficiency of electrons, compounds are needed which can neutralize free radicals by donating their own electrons to free radicals but they themselves do not become free radicals in the process. Pecans, walnuts, hazelnuts, ground nut or peanuts, sunflower seeds contain good amount of antioxidants. 2  Roasted peanuts are far richer in antioxidants than apples, beets and carrots and comparable to the antioxidant content of strawberries and blackberries.

Antioxidant An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction involving the loss of electrons which can produce free radicals. In turn, these radicals can start chain reactions.When the chain reaction occurs in a cell, it can cause damage or death to the cell.he relative importance of the antioxidant and pro-oxidant activities of antioxidants is an area of current research, but vitamin C, which exerts its effects as a vitamin by oxidizing polypeptides, appears to have a mostly antioxidant action in the human body.

Antioxidants Antioxidants can slow, prevent or repair damage to your body cells. While some antioxidants simply control free radicals, others reverse cell damage by transforming free radicals to less damaging compounds or waste products that are eliminated before they can do damage.

Oxidant Oxidant. Definition. noun, plural: oxidants. (1) Any substance that has the ability to oxidize other substance. (2) A molecule or atom capable of accepting electrons during a redox reaction. Supplement. An oxidant is a substance that accepts or receives electron from another substance, hence, is consequently reduced.Since it accepts electrons it is also called an electron acceptor.2) A molecule or atom capable of accepting electrons during a redox reaction.

Antioxidants Antioxidants can protect your body's cells from damaging oxidation much like oil or paint protects your car from rust. Oxidation, which is the loss of an electron, sometimes produces free radicals that can cause oxidative stress or damage to the cells.he Role of Antioxidants: The role of antioxidants in health is inconclusive, because antioxidants research is still relatively new. Your body's cells use antioxidants to scavenge for and counteract the negative effects of free radicals.

Antioxidants Many foods are fortified with antioxidants (e.g. vitamins C, E, the mineral selenium, and beta carotene, which forms vitamin A in the body). However, fresh fruits and vegetables contain other phytochemicals along with antioxidants, making them better choices than cooked or processed foods.

List of antioxidants in food In the following discussion, the term antioxidant refers mainly to non-nutrient compounds in foods, such as polyphenols, which have antioxidant capacity in vitro and so provide an artificial index of antioxidant strength – the ORAC measurement.any common foods contain rich sources of polyphenols which have antioxidant properties only in test tube studies. As interpreted by the Linus Pauling Institute, dietary polyphenols have little or no direct antioxidant food value following digestion.
